I'm really tanked atm.
But to properly balance carbs you need an airflow guage thingee to meter the airflow.

I totally agree

So I havent been able to do a copression test yet but I was talking to my mechanic and he said to run some LPG over the manifold to make sure it has no air leaks. So I did and I found its was leaking on 1 & 6 where it bolts to the head. When i removed the intake manifold I realised it was leaking though the notches in the gasket for the injectors. So my question is.....Is there a gasket for the L28 that doesnt have the notches for the fuel injectors or do I have to get one made???

Cheers Jay

You could try an L26 gasket, JA049 is the NZ Gaskets part number.

Cool Thanks I wondered if they would fit

Sorry to thread hi jack but I needed to ask why 20 times?

I figure 20 times would be a good way to burn out your starter or deaden a battery.

20 revolutions is not much for a starter - especially with the sparkplugs out and as such there is only compression on the one cylinder which you are testing.

However I say 20 revolutions (10 compression strokes) because a gauge normally take 5 or 6 compressions to pump up the gauge and I just allow a few more to be sure.

I was a mechanic for 13 odd years and always did it this way and never had a problem with the method.
